CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Stage of International Patent Application No. PCT/CN2018/093852 filed on Jun. 29, 2018, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

This application relates to the field of terminal technologies, and in particular, to a method for browsing an application folder and an electronic device.

BACKGROUND

An Android (android) operating system is a Linux-based open-source operating system, and is mainly applied to an electronic device (for example, a smartphone or a tablet computer). Currently, for an electronic device with the Android operating system, a user may install various applications on the electronic device, for example, WeChat, a browser, and a camera application. When using an application, the user may save a created, transferred, or downloaded file as required. For example, the file may be audio, a video, a document, a picture, or the like. However, when a large quantity of applications are installed on the electronic device, because folders of the applications are arranged in disorder, and names of the folders are irregular, it is difficult to find a file to be viewed from a plurality of folders when a folder in which the file is stored is unknown. This is greatly inconvenient for the user.

SUMMARY

This application provides a method for browsing an application folder and an electronic device, to help improve efficiency of searching for a file by a user.

According to a first aspect, an embodiment of this application provides a method for browsing an application folder, where the method is implemented on an electronic device having a touchscreen, and specifically includes: detecting, by the electronic device, a first operation on the touchscreen; in response to the first operation, displaying, by the electronic device, a first user interface on the touchscreen, where the first user interface is a setting screen of a first application program, the first user interface includes a folder control, and the folder control is used to indicate a folder of the first application program; detecting, by the electronic device, a second operation on the folder control; and in response to the second operation, displaying, by the electronic device, a second user interface on the touchscreen, where the second user interface is a content details screen of the folder corresponding to the first application program.

In this embodiment of this application, because the folder control can be displayed on the touchscreen, in response to the second operation on the folder control, the electronic device can display the second user interface on the touchscreen. In this way, the user can view, by using the second user interface, content details of the folder corresponding to the first application program. Therefore, compared with the prior art, a scope of searching for the folder corresponding to the first application program is narrowed, to help improve efficiency of searching for a file or a folder.

The following uses an example in which the electronic device is a smartphone for specific description.

For example, FIG. 1 is a possible schematic diagram of a hardware structure of a smartphone. It should be understood that a mobile phone 100 shown in the figure is merely an example of the electronic device, and the mobile phone 100 may have more or fewer components than those shown in the figure, may combine two or more components, or may have different component configurations. Various components shown in the figure may be implemented on hardware, software, or a combination of hardware and software that includes one or more signal processing and/or application-specific integrated circuits.

The mobile phone 100 may include one or more processors 101, a memory 102, a radio frequency (radio frequency, RF) circuit 103, an audio circuit 140, a loudspeaker 141, a microphone 142, a touchscreen 150, one or more sensors 106, and a wireless fidelity (wireless fidelity, Wi-Fi) apparatus 107, a peripheral interface 108, and a power supply apparatus 109. These components may perform communication through one or more communications buses or signal cables (not shown in FIG. 1 ). A person skilled in the art may understand that the hardware structure shown in FIG. 1 does not constitute a limitation on the mobile phone 100. The mobile phone 100 may include more or fewer components than those shown in the figure, or combine some components, or have different component arrangements.

The following describes in detail the components of the mobile phone 100.

The processor 101 is a control center of the mobile phone 100. The processor 101 is connected to parts of the mobile phone 100 by using various interfaces and cables, runs or executes an application program (application, APP) stored in the memory 102, and invokes data and an instruction stored in the memory 102, to perform various functions of the mobile phone 100 and process data. For example, the processor 101 may establish a correspondence between a folder and an application, collect statistics on a most common folder path, and record a latest saved file, a folder path corresponding to the file, and the like.

In some embodiments, the processor 101 may include one or more processing units. An application processor and a modem processor may be integrated into the processor 101. The application processor mainly processes an operating system, a user interface, an application program, and the like, and the modem processor mainly processes wireless communication. It may be understood that, alternatively, the modem processor may not be integrated in the processor 101. For example, the processor 101 may be a Kirin 970 chip manufactured by Huawei Technologies Co., Ltd. In some other embodiments of this application, the processor 101 may further include a fingerprint verification chip, configured to verify a collected fingerprint.

The memory 102 is used to store an application program, data, and various operating systems such as an iOS® operating system developed by Apple and an Android® operating system developed by Google. The memory 102 mainly includes a program storage area and a data storage area. The program storage area may store an operating system and an application program required by at least one function (for example, a sound playing function and an image playing function). The data storage area may store data (for example, a phone book) created based on use of the mobile phone 100. For example, the data storage area may store a photo or a video shot by the user by using the mobile phone 100, or audio recorded by the user by using the mobile phone 100. The data storage area may further store a file such as a picture downloaded by the user, or a document created by the user, or the like. In addition, the memory 102 may include a high-speed random access memory, and may further include a non-volatile memory, for example, a magnetic disk storage device, a flash storage device, or another non-volatile solid-state storage device.

The RF circuit 103 may be configured to send and receive a radio signal in an information sending and receiving process or in a call process. Specifically, the RF circuit 103 may receive downlink data from a base station and then send the downlink data to the processor 101 for processing. In addition, the RF circuit 103 may further send uplink data to the base station. Usually, the RF circuit 103 usually includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, and the like. In addition, the RF circuit 103 may further communicate with another device through wireless communication. The wireless communication may use any communications standard or protocol, including but not limited to global system for mobile communications, a general packet radio service, code division multiple access, wideband code division multiple access, long term evolution, an email, a short message service, and the like.

The audio circuit 140, a speaker 141, and a microphone 142 may provide an audio interface between the user and the mobile phone 100. The audio circuit 140 may convert received audio data into an electrical signal and transmit the electrical signal to the speaker 141, and the speaker 141 converts the electrical signal into a sound signal for output. In addition, the microphone 142 converts a collected sound signal into an electrical signal, and the audio circuit 140 receives the electrical signal, converts the electrical signal into audio data, and then outputs the audio data to the RF circuit 103, to send the audio data to, for example, a mobile phone, or outputs the audio data to the memory 102 for further processing.

The touchscreen 150 may include a touch-sensitive surface 151 and a display 152. The touch-sensitive surface 151 (for example, a touch panel) may collect a touch event performed by the user of the mobile phone 100 on or near the touch-sensitive surface 151 (for example, an operation performed by the user on the touch-sensitive surface 151 or near the touch-sensitive surface 151 by using any suitable object such as a finger or a stylus), and send collected touch information to another component such as the processor 101. The touch event performed by the user near the touch-sensitive surface 151 may be referred to as a floating touch. The floating touch may mean that the user does not need to directly touch the touchpad for selecting, moving, or dragging an object (for example, an App icon), and the user only needs to be near the electronic device to execute a desired function. In an application scenario of the floating touch, terms such as “touch” and “contact” do not imply a direct contact with the touchscreen 150, but a contact near or close to the touchscreen 150. The touch-sensitive surface 151 on which the floating touch can be performed may be implemented in a capacitive type, an infrared light sensing type, an ultrasonic wave type, or the like.

The touch-sensitive surface 151 may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch orientation of the user, detects a signal generated by a touch operation, and transmits the signal to the touch controller. The touch controller receives touch information from the touch detection apparatus, converts the touch information into touchpoint coordinates, and sends the touchpoint coordinates to the processor 101. The touch controller may further receive an instruction sent by the processor 101, and execute the instruction. In addition, the touch-sensitive surface 151 may be implemented in a plurality of types such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type.

The display (also referred to as a display screen) 152 may be configured to display information entered by the user or information provided for the user, and various menus of the mobile phone 100. The display 152 may include two parts: a display controller and a display apparatus. The display controller is configured to receive a signal or data sent by the processor 101, to drive to display a corresponding screen on the display apparatus. For example, in this embodiment of this application, the display apparatus may be configured by using an LCD (liquid crystal display, a liquid crystal display), an organic light-emitting diode (organic light-emitting diode, OLED), or the like. For example, the display apparatus is configured by using an active matrix organic light-emitting diode (active matrix organic light emitting diode, AMOLED).

It should be understood that the touch-sensitive surface 151 may cover the display 152. After detecting a touch event on or near the touch-sensitive surface 151, the touch-sensitive surface 151 transmits the touch event to the processor 101 to determine a type of the touch event, and then the processor 101 may provide corresponding visual output on the display 152 based on the type of the touch event. Although in FIG. 1 , the touch-sensitive surface 151 and the display 152 are used as two independent components to implement input and output functions of the mobile phone 100, in some embodiments, the touch-sensitive surface 151 and the display 152 may be integrated to implement the input and output functions of the mobile phone 100. It may be understood that the touchscreen 150 is formed by stacking a plurality of layers of materials. In this embodiment of this application, only the touch-sensitive surface (layer) and the display (layer) are shown, and another layer is not described in this embodiment of this application. In addition, in some other embodiments of this application, the touch-sensitive surface 151 may cover the display 152, and a size of the touch-sensitive surface 151 is greater than a size of the display 152, so that the display 152 is completely covered by the touch-sensitive surface 151. Alternatively, the touch-sensitive surface 151 may be disposed on a front of the mobile phone 100 in a form of a full panel, in other words, touch of the user on the front of the mobile phone 100 can be sensed by the mobile phone. Therefore, full touch experience on the front of the mobile phone can be implemented. In some other embodiments, the touch-sensitive surface 151 is disposed on a front of the mobile phone 100 in a full panel form, and the display 152 may also be disposed on the front of the mobile phone 100 in a full panel form. Therefore, a bezel-less structure can be implemented on the front of the mobile phone. In some other embodiments of this application, the touchscreen 150 may further include a series of pressure sensor arrays, so that the mobile phone can sense pressure exerted on the touchscreen 150 by the touch event.

The one or more sensors 106 may be a light sensor, a motion sensor, another sensor, and the like. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor may adjust luminance of the display 152 based on brightness of ambient light, and the proximity sensor may turn off a power supply of the display 152 when the mobile phone 100 moves to an ear. As a motion sensor, an accelerometer sensor may detect acceleration values in all directions (usually on three axes), may detect a value and a direction of gravity when the accelerometer sensor is stationary, and may be applied to an application to recognize a mobile phone posture (for example, screen switching between landscape and portrait modes, a related game, and magnetometer posture calibration), a function related to vibration recognition (such as a pedometer and a knock), and the like.

In some embodiments of this application, the sensor 106 may further include a fingerprint sensor. For example, the fingerprint sensor may be disposed on a rear side of the mobile phone 100 (for example, below the rear-facing camera), or the fingerprint sensor is disposed on the front side of the mobile phone 100 (for example, below the touchscreen 150). In addition, a fingerprint recognition function may be implemented by configuring the fingerprint sensor on the touchscreen 150. To be specific, the fingerprint sensor may be integrated with the touchscreen 150 to implement the fingerprint recognition function of the mobile phone 100. In this case, the fingerprint sensor may be disposed on the touchscreen 150, or may be a part of the touchscreen 150, or may be disposed on the touchscreen 150 in another manner. In addition, the fingerprint sensor may be further implemented as a full-panel fingerprint sensor. Therefore, the touchscreen 150 may be considered as a panel on which a fingerprint may be collected at any position. In some embodiments, the fingerprint sensor may process a collected fingerprint (for example, verify the collected fingerprint), and send a fingerprint processing result (for example, whether the fingerprint passes verification) to the processor 101, and the processor 101 performs corresponding processing based on the fingerprint processing result. In some other embodiments, the fingerprint sensor may further send the collected fingerprint to the processor 101, so that the processor 101 processes the fingerprint (for example, verifies the fingerprint). The fingerprint sensor in this embodiment of this application may use any type of sensing technology, including but not limited to an optical sensing technology, a capacitive sensing technology, a piezoelectric sensing technology, an ultrasonic sensing technology, or the like. In addition, for a specific technical solution of integrating the fingerprint sensor into the touchscreen 150 in this embodiment of this application, refer to patent application No. US 2015/0036065 A1, filed with the United States Patent and Trademark Office and entitled “FINGERPRINT SENSOR IN ELECTRONIC DEVICE”, which is incorporated in the embodiments of this application by reference in its entirety. In addition, other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor may be configured in the mobile phone 100. Details are not described herein.

The Wi-Fi apparatus 107 is configured to provide, for the mobile phone 100, network access that complies with a Wi-Fi-related standard protocol. The mobile phone 100 may access a Wi-Fi access point by using the Wi-Fi apparatus 107, to help the user receive and send an email, browse a web page, access streaming media, and the like. The Wi-Fi apparatus 107 provides wireless broadband internet access for the user. In some other embodiments, the Wi-Fi apparatus 107 may also be used as a Wi-Fi wireless access point, to provide Wi-Fi network access for another device.

The peripheral interface 108 is configured to provide various interfaces for an external input/output device (for example, a keyboard, a mouse, an external display, an external memory, or a subscriber identification module card). For example, the peripheral interface 108 is connected to the mouse by using a universal serial bus interface, and is connected to a SIM card provided by an operator by using a metal contact on a card slot of the subscriber identification module card. The peripheral interface 108 may be configured to couple the external input/output peripheral device to the processor 101 and the memory 102.

The mobile phone 100 may further include the power supply apparatus 109 (for example, a battery and a power management chip) that supplies power to the components. The battery may be logically connected to the processor 101 by using the power management chip, so that functions such as charging, discharging, and power consumption management are managed by using the power supply apparatus 109.

Although not shown in FIG. 1 , the mobile phone 100 may further include a Bluetooth apparatus, a positioning apparatus, a camera (for example, a front-facing camera or a rear-facing camera), a flashlight, a micro projection apparatus, a near field communication (near field communication, NFC) apparatus, or the like. Details are not described herein. The front-facing camera may be configured to capture facial feature information, and the processor 101 may perform facial recognition on the facial feature information, to perform subsequent processing.

The following describes the embodiments of this application in detail by using the mobile phone 100 as an example. To help the user search for a file on the mobile phone 100, a folder corresponding to each application installed on the mobile phone 100 may be prompted to the user. In this way, when searching for a file stored by using an application (for example, WeChat), the user can narrow a file search scope, to help improve efficiency of searching for a file by the user.

An Android operating system is used as an example. For example, the Android operating system in this embodiment of this application is shown in FIG. 2 . As shown in FIG. 2 , the Android operating system mainly includes a kernel layer (Kernel), a framework layer (Framework), and an application layer (Applications). In some embodiments, a system runtime library (libraries) layer may further be included between the kernel layer and the framework layer. The system runtime library layer provides support for an upper layer, that is, the framework layer. When the framework layer is used, a C/C++ library included in the system runtime library layer may be invoked to implement a function to be implemented by the framework layer.

The kernel layer is a hardware abstract layer (hardware abstract layer, HAL) between hardware and software, and is an abstraction of specific implementation of a hardware device. The kernel layer may include an input/output device driver (such as a keyboard driver, a touchscreen driver, a headset driver, a speaker driver, and a microphone driver), a universal serial bus (universal serial bus, USB) driver, a device node, and the like. When the user performs an operation on the input device, the input device driver is configured to convert the operation performed by the user on the input device into an input event, and report the input event to the framework layer or the application layer.

The framework layer includes a package manager (package manager), a download manager (download manager), a file system manager (file system manager), a directory manager (directory manager), and the like. The package manager is configured to: after an installation package of an application is obtained, install a corresponding application based on the installation package, and record an installation progress of the application, and the like. After being invoked by an application at the application layer, the download manager is configured to download a corresponding file, record a download progress of the file, and store the file into a specified folder after the file is successfully downloaded. After being invoked by an application at the application layer, the package manager at the framework layer, the download manager, or the like, the file system manager is configured to create a folder in the memory 102 (for example, sdcard) of the mobile phone 100. It should be noted that the directory manager is a newly added module in this embodiment of this application, and may be configured to record a correspondence among a folder name, an application name, and a folder path. For example, if the file system manager creates a folder named “Weixin” in a local folder sdcard of WeChat, the file system manager stores a correspondence among a folder name “Weixin”, an application name “WeChat”, and a path “sdcard/Weixin” of the folder Weixin in the directory manager. For example, a correspondence among “Weixin”, “WeChat”, and “sdcard/Weixin” may be shown in Table 1.

TABLE 1 Application name Folder name File path WeChat Weixin sdcard/Weixin

The application layer includes a native application (native application) (for example, settings, a home screen, and file management) and a third-party application (for example, WeChat) that are installed on the mobile phone 100. The application at the application layer is configured to: receive the input event reported by the input device, perform corresponding processing on the input event, and output the input event by using the output device (for example, a display screen), so that the user can view the input event.

To enable the mobile phone 100 to notify the user of a correspondence between an application and a folder, a related user interface may be displayed on the touchscreen 150 of the mobile phone 100 to notify the user of the correspondence between an application and a folder. An example in which a first user interface is used to prompt a folder corresponding to WeChat is used. If the mobile phone 100 detects a first operation on the touchscreen 150, in response to the first operation, the mobile phone 100 may display the first user interface on the touchscreen 150. The first user interface includes a folder control, and the folder control is used to indicate the folder corresponding to WeChat. If the mobile phone 100 detects an operation on the folder control, in response to the operation, the mobile phone 100 may display, on the touchscreen 150, a content details screen of the folder corresponding to WeChat. For example, the first user interface in this embodiment of this application may be a setting screen corresponding to WeChat.

In an example, as shown in FIG. 2 , the directory manager is added to the framework layer. The directory manager may be configured to store a correspondence among a folder name, an application name, and a folder path. When content stored in the directory manager changes, the change is reported to settings at the application layer, and the settings generates or refreshes the first user interface based on information reported by the directory manager.

For example, as shown in FIG. 3 , in a WeChat installation process, the file system manager at the framework layer creates a root folder Weixin, a subfolder Picture, a subfolder Game, a subfolder Video, and a subfolder Document in a folder sdcard. The subfolder Picture is used to store a picture transmitted by the user in a process of chatting by using WeChat. The subfolder Game is used to store data generated when the user use a WeChat game. The subfolder Video is used to store a video transmitted by the user in a process of chatting. The subfolder Document is used to store a program file related to WeChat running. The file system manager at the framework layer may store a correspondence between a name “Weixin” of the root folder, a name “Weixin” of the application, and the path “sdcard/Weixin” of the root folder in the directory manager at the framework layer.

After storing the correspondence among “Weixin”, “WeChat”, and “sdcard/Weixin”, the directory manager may report the correspondence among “Weixin”, “WeChat”, and “sdcard/Weixin” to the settings (Settings) at the application layer. Then, the settings may generate a first user interface for WeChat based on the correspondence among “Weixin”, “WeChat”, and “sdcard/Weixin”. The first user interface is a user interface that is configured to manage WeChat and that is in the settings, the first user interface includes a control of the root folder Weixin, and the control of the root folder Weixin is used to indicate the root folder. If the mobile phone 100 detects an operation (for example, an operation such as tapping, touching and holding, or heavy pressing) on the control of the root folder Weixin, in response to the operation, the mobile phone 100 displays a content details screen of the root folder Weixin on the touchscreen 150. For example, the content details screen includes a subfolder or a specific file (for example, a picture or a video). In specific implementation, the content details screen may be a user interface for file management.

For example, the first user interface may be a user interface 400 shown in FIG. 4A, and the content details screen may be a user interface 410 shown in FIG. 4B. The user interface 400 includes a folder control 401. The folder control 401 is used to indicate a root folder Weixin. As shown in FIG. 4A, the folder control 401 is an icon of the root folder Weixin. Because the folder control may be implemented by using a folder icon, the first user interface may be simpler, and the user can conveniently view the folder control. In addition, in some other embodiments, the folder control 401 may be a path link of the root folder Weixin, or may be a virtual button, or the like. This is not limited herein.

In some embodiments, the user interface 400 further includes a control 406 configured to return to an upper-level setting menu. The user interface 410 includes a control 402 indicating a subfolder Picture, a control 403 indicating a subfolder Game, a control 404 indicating a subfolder Video, and a control 405 indicating a subfolder Document. The control 402 is configured to receive input of the user, and display, on the touchscreen 150, a user interface including content of the subfolder Picture. The control 403 is configured to receive input of the user, and display, on the touchscreen 150, a user interface including content of the subfolder Game. The control 404 is configured to receive input of the user, and display, on the touchscreen 150, a user interface including content of the subfolder Video. The control 405 is configured to receive input of the user, and display, on the touchscreen 150, a user interface including content of the subfolder Document. The control 401 is used as an example. If the mobile phone 100 detects an operation of touching the control 401 by the user, in response to the operation, the mobile phone 100 may display the user interface 410 on the touchscreen 150. Because the user may perform an operation on the folder control 401, the touchscreen 150 can display the user interface 410, and all controls displayed in the user interface 410 are used to indicate subfolders corresponding to WeChat, the user can determine folders correspond to WeChat. This helps improve, to some extent, efficiency of searching for a file stored in a process of using WeChat by the user.

In addition, in some embodiments, as shown in FIG. 4B, the user interface 410 may further include some function controls, for example, new folder, search, refresh, sort, and more. These function controls help the user easily find and operate a folder.

In some other embodiments of this application, the first user interface for WeChat may alternatively be a user interface 500 shown in FIG. 5 . The user interface 500 includes path information “sdcard/Weixin” of the root folder Weixin and a control 501. The control 501 is configured to receive input of the user, and display a content details screen of the root folder Weixin on the touchscreen 150. For example, the content details screen may be the user interface 410 in FIG. 4B. An example in which the content details screen is the user interface 410 shown in FIG. 4B is used. If the mobile phone 100 detects an operation of touching the control 501 by the user, in response to the operation, the mobile phone 100 may display the user interface 410 on the touchscreen 150. In some other embodiments, the first user interface further includes a control 502. The control 502 is configured to return to an upper-level setting menu.

In some other embodiments, the file system manager at the framework layer may store, to the directory manager, names of subfolders included in the root folder WeiXin, an application name “WeChat”, and paths corresponding to the subfolders. The directory manager reports the names of the subfolders, the name of the application, and the paths corresponding to the subfolders to the settings of the application layer. The settings generates the first user interface based on the names of subfolders, the name of the application, and the paths corresponding to the subfolders. The first user interface includes a control corresponding to each subfolder. In this scenario, a file structure of the root folder Weixin shown in FIG. 3 is used as an example. For example, the first user interface may be a user interface 600 shown in FIG. 6 a -1. The user interface 600 includes a control 602 indicating a subfolder Picture, a control 603 indicating a subfolder Game, a control 605 indicating a subfolder Video, and a control 606 indicating a subfolder Document. The control 602 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Picture. The control 603 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Game. The control 604 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Video. The control 605 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Document. For example, if the mobile phone 100 detects an operation of touching the control 602 by the user, in response to the operation, the mobile phone 100 displays the user interface 610 on the touchscreen 150. The user interface 610 is configured to display content included in the subfolder Picture. In some other embodiments, the user interface 600 further includes a control 601. The control 601 is used to return to display an upper-level setting menu. Because the first user interface directly includes a subfolder control, a folder corresponding to WeChat can be more intuitively prompted to the user, to improve user experience.

During specific implementation, controls in the user interface 600 may be sorted based on a time sequence of latest storage of a file in each subfolder, or may be sorted based on a sequence of initial letters of names of subfolders, or may be sorted based on a sequence of creating subfolders in a WeChat installation process, or may be sorted in descending order of frequencies of storing files in the subfolders, and the like. This is not limited herein. For example, the controls are sorted based on a time sequence of latest storage of the files, if the last time when a picture is saved in the subfolder Picture is May 18, 2018, no file is saved in the subfolder Game, the last time when a file is saved in the subfolder Video is May 30, 2018, and the last time when a file is saved in the subfolder Document is Jun. 1, 2018, in this case, the mobile phone 100 displays, from top to bottom, the controls of the subfolders on the touchscreen 150 in the following order: the subfolder Document, the subfolder Video, the subfolder Picture, and the subfolder Game. In some embodiments, because the subfolder Game does not include a file, the user interface 600 shown in FIG. 6 a -1 may further not include (in other words, not display) the control 603. If the controls in the user interface 600 may be arranged based on the time sequence of latest storage of a file in each subfolder, this helps the user understand time at which the subfolders store files most recently, and helps improve convenience of searching for a file or a folder to some extent.

In some other embodiments of this application, because the subfolder Document is used to store a program file related to running WeChat, but is not used to store a user file, the file system manager may not store the subfolder Document in the directory manager. In this scenario, the user interface 600 shown in FIG. 6 a -1 may further not include the control 605. In the foregoing manner, a range in which the user searches for a file is narrowed, to further improve efficiency of searching for a file or a folder by the user.

In some other examples, the first user interface may further be a user interface 620 shown in FIG. 6 b . For example, the user interface 620 includes a path and a control 622 of a subfolder Picture, a path and a control 623 of a subfolder Game, a path and a control 624 of a subfolder Video, and a path and a control 625 of a subfolder Document. The control 622 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Picture. The control 623 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Game. The control 624 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Video. The control 625 is configured to receive input of the user, and display, on the touchscreen 150, content included in the subfolder Document. For example, if the mobile phone 100 detects an operation of touching the control 622 by the user, in response to the operation, the mobile phone 100 displays the user interface 610 on the touchscreen 150. The user interface 610 is configured to display content included in the subfolder Picture. In some other embodiments, the user interface 600 further includes a control 621. The control 601 is configured to return to display an upper-level setting menu. The user interface 620 shown in FIG. 6 b further includes a path of a subfolder in addition to a control, so that the user can more intuitively learn path information of the subfolder.

In some other embodiments of this application, the file system manager at the framework layer may further collect statistics on a frequency of storing a file in a subfolder at an interval of preset duration, and when storing a name of each subfolder, the name “WeChat” of the application, and a path corresponding to each subfolder to the directory manager, mark a name of a subfolder that is most frequently stored. For example, the subfolder Picture has the highest storage frequency, and a name of the subfolder Picture is marked as Picture-frequency No. 1. In this scenario, the settings at the application layer generates the first user interface based on information reported by the directory manager. For example, the first user interface may be a user interface 700 shown in FIG. 7B. A difference between the user interface 600 shown in FIG. 6 a -1 and the user interface 700 is that a control 707 of a common folder is added. Compared with the user interface 600, the user interface 700 more directly displays the common folder to the user. It may be understood that the user may display, on the touchscreen 150, content of a corresponding part of the user interface 700 by sliding up and down.

To ensure accuracy of the control of the common folder in the user interface 700, the file system manager saves a statistical result to the directory manager at an interval of preset duration. The directory manager compares whether the currently saved statistical result is the same as a previously saved statistical result, and if yes, deletes one statistical result, or if the currently saved statistical result is changed, saves the currently saved statistical result, and deletes the previously saved statistical result. Then, the directory manager reports the current statistical result to the settings, and the settings changes, based on the reported statistical result, the control of the common folder in the user interface 700 to a control of a folder in the statistical result. It should be noted that the preset duration may be correspondingly set based on an actual situation, for example, 2 hours or 30 minutes. This is not limited herein.

In addition, WeChat is used as an example. If the first user interface for WeChat includes controls of all subfolders, in a subsequent process in which the mobile phone 100 runs WeChat, a new subfolder may be created. To ensure reliability of the controls included in the first user interface for WeChat, when the file system manager creates a subfolder for WeChat, for example, the file system manager creates a subfolder Audio in a root folder Weixin, the file system manager stores a name “Audio” of the subfolder, a name “WeChat” of the application, and path information sdcard/Weixin/Audio of the subfolder Audio to the directory manager. The subfolder audio is used to cache an audio file. After detecting that “Audio”, “WeChat”, and “sdcard/Weixin/Audio” are stored, the directory manager reports “Audio”, “WeChat”, and “sdcard/Weixin/Audio” to the settings at the application layer. The settings refreshes the first user interface for WeChat based on “Audio”, “WeChat”, and “sdcard/Weixin/Audio”. For example, if the first user interface before refreshing is the user interface 600 shown in FIG. 6 a -1, the refreshed user interface can be a user interface 800 shown in FIG. 8 . Different from the user interface 600, the user interface 800 includes a control 801, and the control 801 is configured to link to a user interface that displays content included in a subfolder Audio.

To help the user search for a latest file saved in a process of using an application, in some embodiments, after successfully executing a download task, the download manager or the file system manager saves a name of a downloaded file, a name of the application, and a path of the file to the directory manager. After detecting that the information is stored, the directory manager reports the information to the settings at the application layer. In this scenario, the first user interface generated by the settings for the application further includes a file control, and the file control is used to indicate a latest saved file. For example, the first user interface may be a user interface 900 shown in FIG. 9A. A difference between the user interface 900 and the user interface 600 shown in FIG. 6 a -1 is that the user interface 900 further includes a file control 901, and the file control 901 is used to indicate a latest saved file. For example, a latest saved file is a picture that is in the user interface 910 and that includes a name “scenery” is used. If the mobile phone 100 detects an operation of touching the file control 901 by the user, in response to the operation of touching the file control 901 by the user, the mobile phone 100 displays the user interface 910 on the touchscreen 150. It may be understood that the file control 901 may be a zoomed-out picture of the picture whose name is “scenery”, or may be another identifier (such as the name of the picture, “scenery”). This is not limited herein.

When the file system manager or the download manager saves a new file, a name of the newly saved file, a name of an application, and a path of the file are saved to the directory manager. After detecting that the information is stored, the directory manager reports the information to the settings at the application layer. Then, the settings refreshes, based on the information, a control of the latest saved file included in the first user interface.

It should be noted that the first user interface in this embodiment of this application may further be a user interface 1000 shown in FIG. 10 . The user interface 1000 includes controls of all subfolders included in a root folder Weixin, a control of a common folder, and a control of a latest saved file.

In some other embodiments of this application, to simplify an operation performed by the user on the mobile phone 100, so that the first user interface is displayed on the touchscreen 150, a control may be added to a system setting screen for WeChat. When the mobile phone 100 detects an operation on the control, in response to the operation, the mobile phone 100 displays the first user interface on the touchscreen 150. It should be noted that a name of the control is not limited in this embodiment of this application. For example, the name of the control may be application folder management, or may be folder management. The following uses the application folder management as an example.

For example, the system setting screen for WeChat is a user interface 1100 shown in FIG. 11 a -1, and application file management 1101 is added to the user interface 1100. When the mobile phone 100 detects an operation on the application folder management 1101, in response to the operation, the mobile phone 100 displays the first user interface on the touchscreen 150. The operation on the application folder management 1101 may be a touch operation, a touch and hold operation, a heavy press operation, or the like on the application folder management 1101. This is not limited herein. An example in which the first user interface is the user interface 600 shown in FIG. 6 a -1 is used. When the mobile phone 100 detects an operation on the application folder management 1101, in response to the operation, the mobile phone 100 displays the user interface 600 on the touchscreen 150. In response to an operation of touching, by the user, a setting icon included in a home screen, the mobile phone 100 displays the system setting screen on the touchscreen 150. For example, in response to the operation on the setting icon, the system setting screen displayed on the touchscreen 150 by the mobile phone 100 may be a user interface 1120 shown in FIG. 11 b . The user interface 1120 includes WeChat 1121. In addition, the user interface 1120 may further include controls such as a search box, enabling cloud backup, screen locking, wireless and network, and file management. Using a system setting screen shown in FIG. 11 b as an example, in response to a touch operation of the user on WeChat 1121 included in the system setting screen, the mobile phone 100 may display the user interface 1100 on the touchscreen 150.

For example, the home screen may be shown in FIG. 12 . Specifically, the home screen 1200 includes a WeChat icon 1202, a setting icon 1203, a camera icon 1204, a file management icon 1205, a status bar 1201, and a DOCK bar 1206. The status bar 1201 includes a telecom operator identifier (China Mobile), a network standard (4G), time, a Bluetooth icon, remaining power, and the like. In some other embodiments, the status bar 1201 may further include a Wi-Fi icon, an external device icon, and the like. The dock bar 1206 includes a phone icon, an SMS message icon, an email icon, and a weather icon. It should be understood that the user may modify, based on a requirement of the user, application icons included in the DOCK bar.

In addition, for ease of user operation, a control may be further added to a shortcut menu (for example, a POP box) of each application by using a home screen launcher. If the mobile phone 100 detects an operation on the control, in response to the operation, the mobile phone 100 displays the first user interface on the touchscreen 150.

The home screen 1200 shown in FIG. 12 is used as an example. As shown in FIG. 13A, in response to an operation on the WeChat icon, the mobile phone 100 may display a WeChat shortcut menu 1300 on the touchscreen 150. The shortcut menu 1300 includes application folder management 1301, my QR code 1302, scan 1303, collection and payment 1304, and share “WeChat” 1305. It should be noted that the operation on the WeChat icon may be an operation of touching and holding or heavy pressing the WeChat icon, an operation of tapping or double-tapping the WeChat icon, or the like. This is not limited herein. An example in which the first user interface is the user interface 600 shown in FIG. 6 a -1 is used. In response to an operation on the application folder management 1301, the mobile phone 100 may display the user interface 600 on the touchscreen 150.

In some other embodiments, in response to an operation of saving a file (for example, a picture, a video, a document, or audio) by the user, the mobile phone 100 may further display a dialog box on the touchscreen 150. The dialog box is used to prompt the user that the file is saved successfully and whether to view the saved file. For example, a user interface 1400 shown in FIG. 14A is a user interface for chatting with a user Jolin in WeChat. After detecting that the user successfully saves a picture 1401, the mobile phone 100 displays a dialog box 1402. The dialog box 1402 includes an option “Yes” 1403 and an option “No” 1404, and the dialog box 1402 is used to prompt the user that the picture 1401 is successfully saved and whether to view the saved picture 1401. If the mobile phone 100 detects a touch operation on the option “yes” 1403, in response to the operation, the mobile phone 100 displays the first user interface on the touchscreen 150. For example, a file structure corresponding to WeChat is the file structure shown in FIG. 3 . For example, the first user interface is a user interface 1410 shown in FIG. 14B. In response to the touch operation on the option “yes” 1403, the mobile phone 100 displays the user interface 1410 on the touchscreen 150. The user interface 1410 includes a subfolder Picture control, a subfolder Game control, a subfolder Video control, a subfolder Document control, and a file control 1405. Because the file 1401 saved by the user is a latest saved file, the file control 1405 is used to indicate the file 1401 saved by the user. If the subfolder Picture control, the subfolder Game control, the subfolder Video control, and the subfolder Document control are arranged based on a time sequence of latest storage of a file in each subfolder, a position of the subfolder Picture control in the user interface 1410 is before that of another subfolder control. If the mobile phone 100 detects a touch operation on the option “no” 1404, in response to the operation, the mobile phone 100 closes the dialog box. The foregoing technical solution helps the user view a latest saved file.

The foregoing embodiments of this application may be applied to applications installed in the mobile phone 100, and are not limited to WeChat. The foregoing uses WeChat as an example for description. According to the foregoing embodiments, the user searches for a related file in a folder corresponding to an application, and a range in which the user searches for a file is greatly narrowed, to help improve efficiency of searching for a file by the user.

In addition, functions of the directory manager in the foregoing embodiments of this application may be further integrated into the file system manager, and the file system manager reports corresponding information to the settings at the application layer, so that the settings generates and refreshes the first user interface.

It should be noted that WeChat is used as an example. In some other embodiments of this application, a control 1501 may be further added to a setting screen of WeChat. If the mobile phone 100 detects a touch operation on the control 1501, in response to the touch operation, the mobile phone 100 displays the first user interface on the touchscreen 150. For example, the first user interface is the user interface 1410 shown in FIG. 14B. In this case, in response to the touch operation on the control 1501, the mobile phone 100 displays the user interface 1410 on the touchscreen 1501.

It should be understood that the first user interface may be a user interface for managing WeChat in a native application (for example, the settings) installed on the mobile phone 100, or may be a setting screen for managing WeChat in WeChat. This is not limited in this application.

It should be noted that, in this embodiment of this application, a shortcut gesture operation (for example, three fingers swipe up or draw a circle) may be further set, to display the first user interface on the touchscreen 150.

In addition, WeChat is used as an example. As shown in FIG. 16A, if the mobile phone 100 in this embodiment of this application detects a touch and hold or heavy press operation on an icon of a first application program, in response to the operation, the mobile phone 100 displays a shortcut menu 1600 on the touchscreen 150, and the shortcut menu 1600 includes application folder management 1601. In some other embodiments, the shortcut menu 1600 may further include controls such as my QR code, scan, collection and payment, and share “WeChat”. The user may also correspondingly modify the controls included in the shortcut menu 1600 based on a requirement of the user. When the mobile phone 100 detects a touch operation on the application folder management 1601, in response to the touch operation, the mobile phone 100 displays the user interface 1610 on the touchscreen 150. The user interface 1610 is a user interface of content details of a root folder corresponding to WeChat. In specific implementation, the user interface 1610 may be a user interface in native application file management. For example, the root folder corresponding to WeChat includes a subfolder Picture, a subfolder Game, a subfolder Video, and a subfolder Document. The user interface 1610 includes a control 1602 used to indicate the subfolder Picture, a control 1603 used to indicate the subfolder Game, a control 1604 used to indicate the subfolder Video, and a control 1605 used to indicate the subfolder Document.

WeChat is used as an example. In another embodiment, for WeChat, the mobile phone 100 creates a root folder Weixin in a folder sdcard, and the root folder Weixin includes a subfolder Download and a subfolder File. Specifically, the subfolder Download is used to store a picture, audio, a video, and a document downloaded by the user during the use of WeChat. The subfolder File is used to store a program file related to WeChat running. The mobile phone 100 may reclassify files based on types of the files included in the subfolder Download and the subfolder File, to generate the first user interface. The first user interface may be a user interface 1800 shown in FIG. 18 , and includes a control 1802, a control 1803, a control 1804, and a control 1805. In response to a touch operation on the control 1802, the mobile phone 100 may display, on the touchscreen 150, a user interface of a picture corresponding to WeChat. In response to a touch operation on the control 1803, the mobile phone 100 may display, on the touchscreen 150, a user interface of audio corresponding to WeChat. In response to a touch operation on the control 1804, the mobile phone 100 may display, on the touchscreen 150, a user interface of a video corresponding to WeChat. In response to a touch operation on the control 1805, the mobile phone 100 may display, on the touchscreen 150, a user interface of a file corresponding to WeChat. In addition, the user interface 1800 may further include a control 1801, and the control 1801 is configured to return to an upper-level setting menu. The files are reclassified based on types of the files, to facilitate the user to search for a file, and improve efficiency of searching for a file by the user.

The foregoing embodiments in this application may be used in combination, or may be used as an independent embodiment. In addition, the foregoing embodiments are described only by using WeChat as an example. The embodiments of this application may also be applied to another application.

An embodiment of this application further provides a method for copying a file stored in the mobile phone 100 to another device (for example, a personal computer). The following uses a scenario shown in FIG. 19 as an example for detailed description.

As shown in FIG. 19 , after a mobile phone 100 is connected to a computer 1900, a file stored in the mobile phone 100 is copied to the computer 1900.
